Programs are a set of instructions given to a computer. After the
programs are created, they are translated into binary language using a
translator software. This is how different software are built using programs.

The following is the Python program for finding the area of a rectangle.
Each instruction and their functions are indicated.

A value of 80 is given to the variable l.
A value of 60 is given to the variable b.
The product of l and b is given to the variable A.
The value of the variable A is printed.

Now, create a program in Python to find the perimeter of this rectangle.
[Perimeter = 2 x (Length+Breadth)]

IDE (Integrated Development Environment) is an Integrated
software that helps you to write and run various programs. IDLE is a
simple IDE software for creating python programs.

We can open IDLE from the menu Applications –Programming.

This window is called the Python Shell window and the place where
the program is typed is called the shell prompt.

In the Python Shell window, type the command print ("How are
you") and press the Enter key and its output is given below.

In Python program, anything that is given in quotes (eg. “how are
you”), even if they are digits, will be considered as strings.

What output would we get if we type the instructions given in the
table in shell prompt?

Anu has prepared a table containing Maximum and Minimum
temperature of different places in LibreOffice Calc.

Then she found the average temperature of AGRA and it is
recorded in cell E2. For this, she found out the sum of cells C2 and D2
and divided it by two. Here you just have to type = SUM (C2: D2) / 2 and
press Enter.

SUM() is used to find the total in LibreOffice Calc.

Now, can you help Anu in doing the following activities.

1. Maximum temperatures are given in cells C2 to C5. So, what does Anu
have to type to find out their average?

2. Minimum temperatures are given in cells D2 to D5. So, what does Anu
have to type to find out their average?

Look, Hari has done the activity done by Anu in the last worksheet by
using a different function.

Hari has used AVERAGE function here. =AVERAGE(C2:D2) is used to find
out the average of cells from C2 to D2.
Can you find out the average of maximum and minimum temperature by
using the same function.

Maximum temperatures are given in the cells C2 to C5. Then what
should Hari type to get its average?

Minimum temperatures are given in cells D2 to D5. Then what should
Hari type to get its average?

Worksheet - 11 Communications Technology

Let us see the table prepared by Anu and Hari.

There are decimal places in the answers obtained when they
calculated the Daily Mean Temperature. We need to get the same as
integers. How do we get it?

To round off the decimal places the ROUND() function can be used.
You have to just type ROUND (E2,0) to round off the value in E2. Try to do
the activities by selecting the cell (F2) where the result is to be obtained.

=ROUND(E2,0)

This function is meant to round off the values in E2 to zero decimal
places. This can also be done by using average and round function
together. Just give ROUND(AVERAGE(C2, D2),0))

So what will you type to get an integer in C6?

When Anu tried to paste the name of place and average to another
sheet, she couldn’t paste it properly. Why was it so?

These type of issues arise while we try to copy and paste LibreOffice
Calc data having function or formula. We can solve this issue by using the
option Paste Special. All you have to do is change the tick mark given in
the Formulas to Numbers while pasting.

This is the window Anu got when she used the option Paste
Special.

Where should she put tick mark to paste numbers and name of places ?
